It is possible to undertaken larger single storey rear house extensions under permitted development? Or under the Prior Approval route?
Home extensions can provide much needed additional living space for householders. Prior approval for larger extensions allows for up to 6m in length (for attached) or 8m for detached houses, without the need for planning approval, subject to certain limitations and conditions.
These applications require the local planning authority (LPA) to consult with adjoining neighbours. If they object then the LPA would determine impact and decide whether the works should go ahead. This can present uncertainty into the process. Identical proposals could result in different outcomes depending on the views of the relevant neighbours.
The process is be further complicated where there are multiple neighbours. For example, blocks of flats or commercial properties. One of our recent projects was for a simple 3-bedroom semi-detached property. Notifications had to be sent out to 60 different neighbours! This is way in excess of what would normally be required, although we have heard of higher numbers in some London properties.
Liaising with neighbours before a Prior Approval Applications is submitted is vital to have the best possible chance of a positive outcome.
Plande have been involved with numerous applications for Prior Approval for larger home extensions.
